The body moved with acceleration, the modulus of which is a = 2.5m / s during the time interval t = 1.6s. Find the change in the modulus of the body’s velocity over this period of time.
Condition:
a = 2.5m / s.
t = 1.6s.
To find :
V -?
Decision :
V = V0 + a * t.
since V0 = 0.
It follows that:
V1 = a * t
V1 = 1.6 * 2.5 = 4 (m / s).
V = V1-V0.
Answer: 4 m / s.
